PINEAPPLE CORING AND SLICING MACHINE.

Application filed October 12, 1914.

To all whom t may concern Be it known that I, FRED W. WOLF, a citizen of the United States, residing at Honolulu, island of Oahu, Territory of Hawaii, have invented a new and useful Pineapple Coring and Slicing Machine, of which the following is a specification.

The object of my invention is to pro-vide a pineapple slicing and coring machine constructed to perform both operations successively in and automatically by my invention. v

Among the objects kof my invention is the provision of novel slicing means, novel coring means and novel means for holding the pineapple during the coring and slicing operations.

a v It is v-my object lto provide novel elements in such a machine and to combine and arrange the various parts of the machine in a novel and improved way.

' I attain these and other objects of my invention as hereinafter more fully disclosed,

by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of my machine; Fig. 2 is a top plan of the machine;

vjFig. 3 is an end elevation of the body of the machine; Fig. 4 is an enlarged detailed sectional view ofthe turret andV slicing means; Fig. 5 is a vertical sectional view approximately on line 5 5 of Fig. 4. showing the cover plate of the lower knife brace removed; Fig. 6 is a detail sectional view of the coring means, on line 6-'6 of Fig. 4; Fig. 7 lis a detail view of the hub of the turret; Fig. 8 isa detail view-on line 8-8 of Fig..2, showing in detail the Geneva movement; Fig. 9 is an enlarged detail of the outer sleeve guard 48. Y

Like characters of reference refer to like parts throughout the several views.

Referring to the accompanyingy drawings, mounted on a' suitable supporting frame I provide a main driving shaft 2, operated by pulley v1 and clutch 3. Mounted on the main driving shaft f2 is a bevel gear 4 mesh-- Y jing with bevel gear 5 on an upright shaft 7, which4 is supported by bracket 6. Mounted `on the upper. end of the shaft 7 is a crank disk 8, to which isV secured a pitman 9. The opposite end of the pitman 9 is connecto. ed to crosshead 10, the latter being slidable Specification of Letters Patent.

on guide rods 11, which are supported by castings 12 on the frame. Crosshead 10 in turn operates coring tube 40.

On main driving shaft 2 are keyed disks l Mounted on turret shaft 18 is the turret 19, which, as illustrated in Figs. 5 and 1, is composed of a series of novel hooked, starpointed plates or disks 20, spaced apart one from the other by offset ribs 21. The series of disks 20 are held together by bolts 23 and hub members 22 which bolts 23 fasten together. A hub or spacing sleeve 24, mounted on shaft 18 operates to prevent hub members 22 from becoming too tight. The series of disks 20 revolve between two turret castings 25 which are mounted on the main framework of the machine. Spaced diagonal braces 26 are provided, as illustra-ted in Figs. 3 and 4, between which is mounted the lower knife holder 28, toV which is secured the lower end of the turret castings 25, as shown atV 27 in Fig. 3. An upper knife holder 29 is provided, mounted on a shoulder portion 30 of turret casting 25. Rotatably mounted on top of the turret castings as shown at 31 in Fig. 4 is a shaft 32 to which is attached a curved plate mem-- ber 33. It has a pivotal or swinging movement when shaft 32 is partially rotated.

To the end of shaft 32 is attached a cam lever 34, as shown in Fig. 3, to the lower end of which is attached a spring 35, which in turn is fastened to the frame of the machine so vas to hold themember 34 in tension against a cam 36 mounted on the main driving shaft 2. While the fruit vis being cored it is held in the pocket formed between the hooked star ends of the turret plates or disks 20 by plate 33. A stationary cover plate 37 is fastened to` the turret castlngs 25 forward of the liap or cover plate I provide means for slicing the pineapples, comprising long narrowknife blades 38,V positioned, between adjacent turret platesor disks 20 and penetrating the turret to a'depth slightly greater than the depth of the pockets formed between the hooked star' portionsof plates or disks 20, so as to guard 41 encircling coring tube 40 is mounted between casting 12 and turret casting 25 (Figs. 2 and 6). Coring tube 40 has a sharpened mouth 42. For the reception ofy the mouth /42 of coring tube -40 I provide a coring knife guide 43. This member has an annular groove 44 which encircles a central core 45, over which the mouthV of the coring tube 40 projects as it vcompletes its coring stroke, thus preventing dulling of the sharpened mouth 42 and pushing the cored portion of the pineapple farther i'nto the coring tube, and ultimately discharging successive cores Vfrom the opposite end of the coring tube. An outer sleeve guard 48 Y v protecting the outer end of coring tube 40,

projects from the frame, Vas shown in Fig. 9.`

Fig. 7 illustrates the clamping means 46 by which turret hub members 22 are held fast to turret shaft'18.

-In operation, the pineapples, which have previously been suitably prepared (pared and trimmed), are fed into the turret by suitable means suchas chute A and receivedY in the pocket, as atV B in Fig. 4, between successive hooked star portions of turret disks or plates 20. |Ihe fruit is carried forward as the turret revolves step by step, regulated by thev GenevaV wheel 17, until it reaches the coring position, indicated by C. While the shaft 2`i`s'making one revolution, the Geneva wheel 17 and the turret 19 aremoved forwardone step or pocket and then locked in a temporarilyiixed position by locking hub 15 engaging with the curved surface of the f Geneva wheel 17. The crank disk 8 is so timed with the main driving shaft 2 that thc coi-ing tube 40 is pushed through the fruit while the turret is locked or stationary, the'- fruit `being held by plate 33. I

After the coring operation the nextstep or movement of the turret 19 bringsthe pine.n apple in contact with knife blades 3S'and Y partially slices-the pineapple, as illustrated at D in Fig. 4. The following intermittent movement of theturret 19Vcomplctes the slicing of thepineapple as shown at E, and by its -own weight the cored and sliced pine? apple releases itself from the turret 19 intoV a'discharge device or hopper F' where it is deposited on a belt conveyer and carried Vto the assorting tables.

In my machine the pineapples remain in ahorizontal position throughout the coring and slicing operations.
